One of the two headlight bulbs in your VW Jetta can burn out at any time, but you should expect to wait for both bulbs to fail before replacing them. Although it is possible to change

VW Jetta headlight bulbs yourself, this process will be very inconvenient because one bulb tends to go out shortly after another. If you want your VW Jetta headlights working efficiently and effectively, consider having a professional do the replacement job instead.

What You’ll Need

Before you begin replacing your VW Jetta headlight bulbs, make sure that you have the necessary tools for this job. Not only will you need a new bulb, but you’ll also need some replacement adhesive or lubricant to ensure the bulb stays in place after installation. And of course, when swapping out broken lights you should always work with safety in mind and wear protective eyewear and gloves whenever possible.

The reason that one bulb dies before the other in a pair is simple: several components within your vehicle function only when they receive power from both bulbs simultaneously.

Thus, if one light goes out before its partner, it could interfere with several other systems in your car.

The most common reason for the second light to go out soon after the first is overheating due to a lack of airflow within your Jetta’s headlight assembly. When one light burns out, it leaves an open space where air can pass through freely.

Even though you will have adjusted your Jetta’s headlights to shine directly on the road ahead, they are no longer being shielded by that dead bulb and can get very hot. The heat causes the filaments inside to expand, and they will eventually touch one another. This causes an electric arc to pass between them, which instantly burns out the second light.

Your Jetta’s cooling fan absorbs this problem by pulling air in through the slots at your headlight assembly’s base. Cooler ambient air from outside travels towards the dead light, which causes the filaments to cool down. This prevents them from touching one another and shorting out.

You can prevent overheating by simply changing your headlight bulbs more often. If you drive on roads that are especially dark, there is a slight chance that your lights could fail if they get too hot during normal operation, but you can prevent this by choosing bulbs with a higher wattage rating.

Be sure to drive safely, and if you need help, you can always contact us at 1-800 DRIVING for advice on maintaining your vehicle so it runs smoothly for many years to come!

An excess of heat will lead to certain chemical reactions inside the remaining headlight bulb causing it to burn out soon afterward. The same problem occurs when moisture builds up around one bulb due to poor sealing or improper installation at the factory–moisture can lead to corrosion which can cause the other headlight bulb to fail.

The only way to avoid burning out both bulbs is to ensure that they receive equal cooling and moisture protection while installed in your VW Jetta’s headlights; follow your vehicle owner’s manual for directions on how to do this safely.

If you are not comfortable performing these measures yourself, take the car to a Volkswagen dealer or authorized repair shop before one of your VW Jetta headlight bulbs burns out completely.

The VW Jetta headlight bulb size chart allows you to find the most appropriate replacement bulb size for your vehicle’s lighting system. You may wish to replace your headlamp bulb with a HID or Xenon headlight kit or some Light Emitting Diode or SMD bulbs in place of your interior lighting bulbs.

All of these processes are detailed within the Volkswagen Jetta headlight bulb replacement guide. It combines all the bulb size and replacement guides that you need giving online visitors a free resource that saves them time.

Make good use of the replacement guide whenever you need to change a burnt out light bulb, install LED light bulbs, replace your headlight bulbs, or install a new HID conversion kit.

The information is available to all online users but provides no warranty. It should, therefore, be used at owner’s risk. Make verifications whenever you’re replacing your VW Jetta headlight bulbs to confirm that you have the right bulb sizes, wattages, and voltages.
